Metallic nanoparticles are widely used due to their superior electrical, antimicrobial, and electromagnetic shielding characteristics. In this work, the surface functionalization of polypropylene (PP) fibers using magnetron sputtering with pure Cu and Ag targets in the presence of Ar gas was systematically investigated, in detail, in terms of surface morphology, tensile, abrasion resistance, moisture regain, antibacterial, and electrostatic properties. The results indicated that the nanocomposite films deposited on the PP surface were even and dense under proper treatment conditions. Compared with pristine fiber, breaking tenacity, abrasion resistance, and antibacterial properties of the Cu/Ag-deposited PP fibers were significantly improved, whereas the extension at break and moisture regain decreased in different degrees. Also, the electrostatic property of treated PP fabrics was studied. This work reveals that surface functionalization of Cu/Ag-deposited PP fiber is versatile, and the surface treatment that uses metallic nanoparticles by magnetron sputtering is a promising approach for achieving multifunctional textiles.
The liquid transport capacity in a fibrous textile is of great crucial in comprehensively assessing the final moisture management. In this work, several materials were prepared based on cotton rovings by regulating some technological parameters such as twist and ply number, and the effects of the above key parameters on vertical wicking behavior of cotton roving-based materials were investigated. To effectively improve the wicking rate of materials, three hydrophilic schemes were introduced. The experimental results indicated that the maximum vertical wicking height was obtained when samples treated with a mixed solution of 1.5% JFC and 3% NaOH. Subsequently, several cotton roving-based materials were fabricated based on the optimized hydrophilic treatment. It was found that, the as-prepared materials exhibit a twist-reduced wicking effect, and a ply number-strengthen effect. Furthermore, the underlying mechanisms in the above two cases were unraveled. Finally, our prepared cotton roving-based materials served as a nutrient absorbing medium were demonstrated. Such work provides certain support for an in-depth understanding of wicking behavior of microporous textile structures.
Miscanthus
floridulus
fibers obtained from the
seed floss of
M. floridulus
(a perinneal
plant of Gramineae native to Africa and Asia and widely
distributed in tropical and subtropical regions) have potential application
value in textile and other fields. At present, the biological characteristics
and ecological benefits of
Miscanthus floridus
have been extensively studied by researchers, but there have been
no literature on
M. floridus
fibers.
In order to make reasonable use of
M. floridus
fibers, their morphological structure, physical properties, chemical
composition, thermal insulation properties, and surface absorption
properties were explored in detail in this study. The results showed
that the
M. floridus
fiber is fine
and short and has a hollow structure with a density of 0.67 g cm
–3
. Chemical analyses revealed that the main constituents
of the fiber are cellulose (66.98%), hemicelluloses (13.86%), lignin
(6.97%), pectin (1.99%), and wax (4.38%). The fill power and warmth
retention performance of the fiber are similar to those of wool. In
particular, the
M. floridus
fiber surface
has hydrophobic and lipophilic properties with a static contact angle
of 123.7° for water droplets in equilibrium. Therefore, the
M. floridus
fiber has a promising application prospect
in bulk textile thermal insulation and oil–water separation
fields.
